Senior Machine Learning Engineer

About Our Client
Our client is revolutionizing healthcare by streamlining knowledge workflows with AI. They reduce administrative burdens and elevate outcomes, empowering professionals to focus on what truly matters — improving lives. They’re growing fast and looking for bold, driven teammates to join them.
The Opportunity
Our client is seeking a hands-on ML/LLM Engineer who’s excited to ship real-world applications — not just benchmarks. You’ll help build and optimize AI-native systems that blend structured and unstructured data to power decisions in high-stakes domains. This is a mid to senior-level role for someone ready to go deep on applied ML problems — from retrieval to routing to generation — and ship solutions that deliver measurable impact.
What You’ll Do
Own and optimize pipelines that combine classical ML and LLM-based systems (RAG, scoring, summarization, etc.)
Fine-tune and evaluate LLMs using both open-source and proprietary data
Collaborate with product and engineering teams to build real-world applications in healthcare and biopharma
Implement retrieval strategies, prompt chaining, and inference orchestration for production use cases
Monitor and improve model quality, latency, explainability, and safety
Stay ahead of the curve in LLM evaluation, tuning, and agent-based architectures
Qualifications
5+ years of experience in applied ML, with at least 1–2 years working with LLMs
Strong Python skills and familiarity with ML/LLM frameworks (PyTorch, Transformers, LangChain, LlamaIndex, etc.)
Comfort with embeddings, vector search, retrieval pipelines, and prompt tuning
Bias for experimentation, clarity, and pushing solutions into production quickly
Understanding of responsible AI practices, model evaluation, and observability
Experience in healthcare, compliance-sensitive data, or regulated environments
What Our Client Offers
Opportunity to make a real impact on the future of healthcare
Autonomy, ownership, and growth potential
100% employer-paid health, vision, and dental insurance
Retirement plans (401k), disability insurance, and employee assistance programs
